Objective To observe the change of learning and memory and the expression change of GABAR1 and N-methyl-D-aspartate receptor 2B (NMDAR2B)in right frontal lobe of the brain of the aged rats after the inhalation of sevoflurane.Methods Fifty male SD rats were randomly divided into control group (group C,n=10)and experimental group (group T,n=40).The control group received air at room tempreture.Experimental groups were divided into two groups:group T1 (2 h)and group T2 (4 h)according to the time of inhalation of sevoflurane at 3% concentration.Ev-ery group was equally divided into two groups and Morris water maze was performed on day 1 and day 7 after sevoflurane inhalation.Then the right frontal lobe was gathered and the mRNA transcription and protein expression of GABAR1 and NMDAR2B were detected by Quantitative Real-time PCR and immunofluorescence technique.Results Compared with group C,the escape latency was prolonged in groups T1 and T2 after 1 day of inhalation of sevoflurane (P<0.05),and the times of space explora-tion reduced (P<0.05).mRNA transcriptional and protein content of GABAR1 were significantly upregulated in frontal lobes of groups T1 and T2,mRNA transcriptional and protein content of NMDAR2B were significantly down-regulated (P<0.05).After inhalation of sevoflurane for 7 days, the protein expression of NMDAR2B in the frontal lobe of group T1 was lower than that of group C (P<0.05).In group T2,the escape latency was prolonged (P<0.05),the number of space explo-ration traversals was decreased (P<0.05),the expression of GABAR1 protein in frontal lobe was up-regulated (P<0.05),and the expression of NMDAR2B protein was down-regulated (P<0.05), and the amplitude was higher than that in group T1 (P<0.05).Conclusion Continuous inhalation of sevoflurane can reduce the spatial memory ability of aged rats,and the effect of prolonged inhalation is greater and longer.This effect is related to the expression of neurotransmitter receptors such as GABAR1 and NMDAR2B in the frontal lobe.

Objective To evaluate the efficacy and safety of the mobilization and collection of unrelated allogeneic peripheral blood stem cells. Methods The suitable stem cell mobilization plan was made in accordance with the hematopoietic stem cell mobilization plan of China Marrow Donor Program, the ruler of the hospital, and the donor's constitution. The unrelated allogeneic peripheral blood stem cells of 64 healthy donors were collected in the second Hospital of Shanxi Medical University from May 2012 to January 2017. The donor was infected one or several times with the mobilization agent granulocyte colony stimulating factor (G-CSF) by 5-10 μg·kg-1·d-1. After 3-4 days, peripheral blood hematopoietic stem cells were collected using COBE Spectra blood cell separator. Then, the effect and adverse reaction of donors were analyzed from different age and sex. Results It can achieve the acquisition requirements using 3 or 4 days of mobilization programs, mononuclear cells≥5.0×108/kg, CD34+cells≥2.0×106/kg. The single acquisition success rate (the target acquisition of the number of mononuclear cells and CD34+) up to 65 ％, collection efficiency reached 52％, which could reduce the risk of donor and the cost of patients. The quality of donor stem cell of young was better than that of older persons. Sixteen donors (25％) had mild adverse reactions, and no special treatment was required. Conclusions Allogeneic stem cell mobilization is safe. Starting from save medical resources and the interests of the donor the 3 day or 4 days of mobilization scheme could improve the success rate of the single mobilization. During the collection process, the condition of donor hypocalcemia should be observed and health education should be given to relieve the tension of donor.

Food allergy are triggered by an abnormal immune response to specific food components, with milk and eggs being the most common food allergens, especially in children. Food allergy can cause various symptoms such as rashes, difficulty breathing, and digestive issues. Allergen component diagnostics is a technique used to identify specific allergenic proteins, aiding doctors in providing more precise treatment and management recommendations for patients. This article analyzes the latest research developments and clinical significance of milk and egg allergen components based on the " Molecular Allergology User′s Guide 2.0 (MAUG 2.0)" issued by the European Academy of Allergy and Clinical Immunology (EAACI), including their applications in clinical diagnosis, treatment, and management. This article aims to enhance healthcare professionals′ understanding of milk and egg allergies, offering new perspectives and practical guidelines for research and clinical practice to promote accurate diagnosis and personalized treatment strategies.

Shellfish, being one of the eight major food allergens, affects approximately 3% of the global population. The occurrence of shellfish allergy is not only related to the individual′s immune system sensitivity but is also influenced by geographical environment, food availability, and dietary habits. Although crustaceans (such as shrimp, crab, and lobster) and mollusks (such as oysters, mussels, and squid) are collectively referred to as shellfish, they exhibit significant differences in biological evolution and the spectrum of allergenic molecules they contain, leading to various allergic reactions. Accurate identification of allergenic proteins is crucial for the diagnosis and management of shellfish allergies, with key allergenic protein families including tropomyosin, arginine kinase, and hemocyanin. Furthermore, due to the diversity of shellfish allergens and their cross-reactivity with dust mite and insect allergens, diagnosing and managing shellfish allergies is complex, especially concerning tropomyosin and arginine kinase protein families. Currently, there are no specific immunotherapy treatments for shellfish allergies, and clinical management primarily relies on avoiding allergens and using anti-allergy medications. This article thoroughly interprets the " Molecular Allergology User′s Guide 2.0 (MAUG 2.0)" published by the European Academy of Allergy and Clinical Immunology (EAACI) and the latest research on shellfish allergies both domestically and internationally. It highlights the significant role of allergen component diagnostics in optimizing the diagnostic and treatment processes for shellfish allergies, effectively assisting clinicians in accurately identifying common allergens and cross-reactions, thereby providing patients with more personalized diagnosis and treatment plans.

Vegetable and fruit allergies are common types of food allergies worldwide, most of them are triggered by primary sensitization to pollen. Most allergens in vegetables and fruits belong to a few cross-reactive proteins such as PR-10 proteins, profilins, and nsLTPs. The presence of these allergens in various plants can lead to widespread cross-reactive allergic responses. Component-resolved diagnostics (CRD) can improve diagnostic accuracy by precisely identifying specific allergenic proteins, aiding physicians in making more accurate treatment and management decisions, and reducing unnecessary food avoidance. This article, based on the "Molecular Allergology User′s Guide 2.0 (MAUG 2.0)" issued by the European Academy of Allergy and Clinical Immunology (EAACI), analyzes the primary mechanisms, relevant allergens, and diagnostic and clinical management strategies for vegetable and fruit allergies. By detailing and analyzing these allergenic components, this article may help the healthcare professionals to deep the understandings of vegetable and fruit allergies, offer new perspectives and practical guideline for the research and treatment of these allergies, and promot the development of precise diagnostics and personalized treatment strategies.

Wheat and buckwheat allergies are common food allergies that significantly impact patients′ quality of life and health. Wheat allergy encompasses various forms, including wheat food allergy, exercise-induced allergic reactions (WDEIA), baker′s occupational asthma/allergy, and contact urticaria. IgE-mediated allergic reactions involve sensitization to stable wheat allergens such as ω-5 gliadin and gluten. Although buckwheat allergy is less common, it is gaining attention in certain regions. Allergen component diagnostic technologies, by detecting specific allergen components [e.g., ω-5 gliadin, gliadins (α, β, γ), and Tri a 14], offer precise allergen source identification, aiding in the optimization of diagnosis and management processes. Oral challenge tests are considered the gold standard for diagnosing wheat allergy, and combining skin prick tests with specific IgE measurements can enhance diagnostic accuracy. While avoidance of allergens remains the primary management strategy, research into immunotherapy is ongoing. Future research should focus on a deeper understanding of the structural and immunological characteristics of wheat and buckwheat allergens to develop more accurate diagnostic tools and treatment methods, thereby improving allergy management and patient quality of life. This article provides a detailed interpretation of the Molecular Allergology User′s Guide 2.0 (MAUG 2.0) published by the European Academy of Allergy and Clinical Immunology (EAACI) and recent research advances on wheat and buckwheat allergies, highlighting the crucial role of allergen component diagnostics in optimizing food allergy diagnosis and treatment processes, supporting clinicians in accurately identifying common allergens and their cross-reactivity, and formulating more personalized treatment plans for patients.
